In order to study fire behavior of composites used in the aeronautic field, a kerosene-flame burner has been designed and built allowing to thermally stress one side of small samples with a flame, reproducing the scenario of an engine fire. The burner has been optimized to obtain the same conditions as in standard tests, flame temperature of 1100 °C and heat flux of 116 kW/m². During the tests, the temperature of the rear face is measured with an infrared camera, and the mass loss with a weighting cell. An original method has been developed in order to determine the convective coefficient of the flame on the composite samples as well as the contribution of the radiative part of the total heat flux. It uses the thermal balance of a thin steel plate heated by the flame. The bench test was used to analyze the fire behavior of two carbon fiber reinforced polymer composites, a first one with thermosetting matrix (epoxy 8552) and a second with a thermoplastic matrix (polyphenylene sulfide). The results are shown and analyzed. The comparison will highlight the differences observed in terms of behaviour of composites exposed to a kerosene flame.

为了研究航空领域中使用的复合材料的着火行为，已设计并制造了一种煤油火焰燃烧器，该燃烧器允许用火焰对小样本的一侧进行热应力处理，从而重现发动机着火的情况。燃烧器经过优化，可达到与标准测试相同的条件，火焰温度为1100°C，热通量为116 kW / m ²。在测试过程中，使用红外热像仪测量背面温度，并使用称重传感器测量质量损失。为了确定复合样品上火焰的对流系数以及总热通量的辐射部分的贡献，已经开发了一种原始方法。它利用由火焰加热的薄钢板的热平衡。台架试验用于分析两种碳纤维增强聚合物复合材料的防火性能，第一种具有热固性基质（环氧树脂8552），第二种具有热塑性基质（聚苯硫醚）。结果被显示和分析。比较将突出显示在暴露于煤油火焰的复合材料的行为方面的差异。
